Not to mention each voltage has its max current rating. CPU about 100 watt on 3.3v on full load. GPU about 80 watts 12v on full load Optical drives 20 watts 12v each Harddrives 30 watts 12v and 5v each North Bridge 50 watts 3.3v South Bridge 30 watts 3.3v Did you know that electrical components leak power, so you have to be prepared. |

| 614105 | 2007-11-23 07:48:00 | Each company has its own oem so they could change their mind on cutting costs. Or their could be fake products. | JUST INSANE (6682) | ||
| 614106 | 2007-11-23 08:00:00 | CPU about 100 watt on 3.3v on full load. On the 12v rail you.....gotta stay civil....3.3v was the old CPUs or was it 5v even?.....today they use 12v rails. And not all CPUs consume 100W you jackass. The Pentiums probably did, but saying C2Ds consume 100W is just stupid. GPU 80W? Again, not all, as there are many GPUs that do not need the extra power cable, and those that need even 2 extra power cables (PCI-E cables). I'm not sure about the drives, but 30W on the HDD sounds a bit too much. Maybe around 20? And N/S bridges using 50W? Where do you keep spouting all this crap from? |

| 614108 | 2007-11-23 08:05:00 | Opinion? You're passing down these info as facts. | qazwsxokmijn (102) | ||
| 614109 | 2007-11-23 08:05:00 | I said on 3.3 rail not actual the voltage inverters change it to 1.3 volts | JUST INSANE (6682) | ||

Oh dear. First thing's first - the CPU runs off the 12V rail. The north/south bridge use nowhere near 80W. Remember we're talking "bare minimum" here, not QX6850 type stuff. This adds to just under 300W once the figures are adjusted to be within reason, meaning that a 400W power supply is ample. 500W to be safe. Naturally, the 12V rail is an important consideration too. We're looking at about 200W, which calls for about 17A on the 12V rail. Any decent 400W power supply will be rated at more than this, but as I said, a 500W one is a good idea to be safe and leave a nice margin. Now tell me about these leaky components, please. Where does this power leak to, exactly? |

| 614112 | 2007-11-23 08:09:00 | I said on 3.3 rail not actual the voltage inverters change it to 1.3 volts Sure they do. The voltage inverters also change electricity into a cup of coffee for you in the morning. No body knows man, your not from those companies so you cannot know exact info. I can guarantee you he knows more than you. |

| 614113 | 2007-11-23 08:10:00 | If you take physics then one way of leaking electricity is through the pathways as metals have resistance and the cpu, gpu transistors usually leak since they keep on changing circuitry designs such as die shrink in nano metres | JUST INSANE (6682) | ||
